First the positive.... Effie (owner) and Buk are warm, welcoming, and always ready and willing to help. Extremely comfortable room, and extremely clean and pleasant toilet and shower rooms.
Now the negative...I would expect a hostel to have a warm and inviting lounge or "common room" with sofas and armchairs where travelers can talk and spend the evening. There is a large entrance room, but unfortunately it's 80% taken up with... a billiard table. 90% if you count the locals who play every evening until midnight (rather noisily), bending over to make their shots. It's not pleasant to be sitting in a chair against a wall and have their butts in your face. I was there for a week and rarely saw hostel-dwellers using the pool table... the locals who played every night. I never felt comfortable sitting in that room (on bar stools and high tables around the perimeter) with the billiard activity that totally dominated the room.
So I think that Effie needs to decide: hostel or pool hall?
